A family of Microsoft relational database management systems designed for ease of use.
I'm using :
Microsoft Access for Office 365 MSO (16.0.12527.20612) 32-bit
After selecting one or more colunms in the query designer and then clicking either the 'insert columns' or 'delete columns' icons from the standard toolbar nothing happen. No empty columns are inserted or no columns are deleted.
To delete columns you can of course just hit delete but to insert columns I've had to add the 'insert columns' icon to the quick access menu.
